Info
PIAS®-HN self-piercing nuts are designed to meet high strength thread requirements in thicker panels, with thread
sizes ranging from M5 to M12 and are available in property class 10 material. They can be specified for panels
ranging from 2.0mm to 4.0mm. The Pias® installation tooling system is required to install Pias® nuts.
Available in metric thread sizes in strength class 10 steel, they can be supplied as unplated or with a range of electro
plated zinc finishes including zinc/clear, zinc/nickel and zinc/thick film passivated.
Benefits of Pias® HN Nuts include:
•
Self piercing so no need to pre-punch the hole, meaning one less process is required and there is no potential
for misalignment between hole and nut
•
Reliable, flexible installation process
•
High torque values
•
No surface distortion
•
Various feeding options available
•
Can be specified with a self-locking thread
